前段时间突然发现blog的post to qzone的插件不能使用了，返回的异常如下：

File "C:/Python25/lib/smtplib.py", line 591, in login
    raise SMTPAuthenticationError(code, resp)
SMTPAuthenticationError: (334, 'UGFzc3dvcmQ6')

通过抓包发现stmtp.qq.com

connect: ('smtp.qq.com', 25)
connect: ('58.251.150.237', 25)

发现邮件服务器返回的是 AUTH=LOGIN，多了一个'=',打开smtplib.py找到

elif authmethod == AUTH_LOGIN:
    (code, resp) = self.docmd("AUTH",
        "%s %s" % (AUTH_LOGIN, encode_base64(user, eol="")))
    if code != 334:
        raise SMTPAuthenticationError(code, resp)
    (code, resp) = self.docmd(encode_base64(password, eol=""))

修改为：

elif authmethod == AUTH_LOGIN:
    # Three stage: 1. sent "AUTH LOGIN"; 2. sent "user name"; 3. sent "password".
    (code, resp) = self.docmd("AUTH", AUTH_LOGIN)
    if code != 334:
        raise SMTPAuthenticationError(code, resp)
    (code, resp) = self.docmd(encode_base64(user, eol=""))
    if code != 334:
        raise SMTPAuthenticationError(code, resp)
    (code, resp) = self.docmd(encode_base64(password, eol=""))

找到

if method in authlist:
    authmethod = method
    break

修改为：

if method in authlist or ('=%s' % method) in authlist:
    authmethod = method
    break

最好是将此文件另存到你的项目文件里调用，这样就不需要换个环境就先要修改smtplib.py.
